'0.8.0.dev5661' and there is still a bug:
======================================================================
FAIL: test_pbdv (test_basic.TestCephes)                              
----------------------------------------------------------------------

    raise AssertionError(msg)
AssertionError:

BWT, is there a way to compile scipy/numpy in debug mode and to run it
under valgrind?
